CURRICULUM TOOL: GEOLOGIC HISTORY
GEOLOGIC AGE
NYS Earth Science Core Curriculum
Performance Indicator 1.2 Describe current theories about the origin of the universe and
solar system.
Major Understandings:
1.2j Geologic history can be reconstructed by observing sequences of rock types and
fossils to correlate bedrock at various locations.
 The characteristics of rocks indicate the processes by which they formed and the
environments in which these processes took place.
 Fossils preserved in rocks provide information about past environmental conditions.
 Geologists have divided Earth history into time units based upon the fossil record.
 Age relationships among bodies of rocks can be determined using principles of
original horizontality, superposition, inclusions, cross-cutting relationships, contact
metamorphism, and unconformities. The presence of volcanic ash layers, index
fossils, and meteoritic debris can provide additional information.
 The regular rate of nuclear decay (half-life time period) of radioactive isotopes
allows geologists to determine the absolute age of materials found in some rocks.
Performance Indicator 2.1 Use the concepts of density and heat energy to explain
observations of weather patterns, seasonal changes, and the movements of Earth’s plates.
Major Understandings:
2.1o Plate motions have resulted in global changes in geography, climate, and the
patterns of organic evolution.

Some Past Part A Questions
1. The graph shows the decay of a radioactive material over time.
How long does it take for this radioactive material to decay
through 2 half-lives?
(1) 1 x 103 years
(3) 10 x 103 years
(2) 5 x 103 years
(4) 40 x 103 years

CURRICULUM TOOL: GEOLOGIC HISTORY
GEOLOGIC AGE
Base your answers to the following 2 questions on the block diagram below, which
shows bedrock units A through F and boundary XX’.
2. The rock that formed in the contact metamorphic zone between rock unit E and rock
unit D is
(1) hornfels
(3) schist
(2) marble
(4) anthracite coal
3. Which sequence best describes the geologic history, from oldest to youngest, that
occurred at this site?
(1) deposition of F, D, C, D  intrusion of E  uplift and erosion  deposition of A
(2) intrusion of E  deposition of F, D, C, B  uplift and erosion  deposition of A
(3) deposition of F, D, C, D  uplift and erosion  intrusion of E
(4) deposition of F, D, C, D  intrusion of E  uplift and erosion
